<p>A particle vibrates in simple harmonic motion along a vertical line between y1 and y2 as shown in the figure below. y = 0 is the equilibrium position. (Hint: Consider the relationship between acceleration and displacement for a particle in simple harmonic motion. Assume up along the screen is the positive direction.)<br />(a) Which of the following is true when the particle is at the highest point in its oscillation (y1)? (Select all that apply.)<br />1<br />zero velocity maximum negative velocity maximum negative acceleration maximum positive velocity zero acceleration maximum positive acceleration<br /><br /><br />(b) Which of the following is true when the particle is at the equilibrium position (y = 0) and is on its downward journey? (Select all that apply.)<br />2<br />zero velocity maximum negative velocity maximum negative acceleration maximum positive velocity zero acceleration maximum positive acceleration<br /><br /><br />(c) Which of the following is true when the particle is at the lowest point in its oscillation (y2)? (Select all that apply.)<br />3<br />zero velocity maximum negative velocity maximum negative acceleration maximum positive velocity zero acceleration maximum positive acceleration</p>
